How GST Invoicing Works
Three things drive your GST invoice — who you're selling to, where they are, and what the rate is.
Enter seller & buyer details
Your GSTIN, the buyer's GSTIN, and both states determine whether CGST+SGST (same state) or IGST (different states) applies — calculated automatically.
Add items with HSN codes
Each item gets an HSN or SAC code, qty, rate, and GST rate. Taxable value and GST amount are computed per line and summed at the bottom.
